Seconding this. Make sure you have all the other basic stuff checked - routine, good diet, a friend or 2 with above room temperature IQ, productive pursuits, etc.
Also, as per forum rules I can't suggest anything illegal but it might be a very very good idea to read up on pot edibles. Changed my life in a way that most people can't appreciate unless they've experienced 15 years of lying in bed for hours every night with a million useless racing thoughts. Now it takes 15 minutes to catch those sweet sweet zzzs. During the day I'm focused and mellow, Thai shenanigans don't matter so much anymore. No withdrawals even if going cold turkey after many months of daily use. Maybe a hospital here can prescribe you with oil drops? Anxiety and insomnia are 2 conditions they can prescribe them for. If not, most Thais are capable of finding some provider on Twitter/Instagram for you. Good luck.
